## Description
<section id='description'>
Sometimes you will need to build a string, <a href="https://en.wikipedia.org/wiki/Mad_Libs" target="_blank">Mad Libs</a> style. By using the concatenation operator (<code>+</code>), you can insert one or more variables into a string you're building.
</section>

## Instructions
<section id='instructions'>
Set <code>myName</code> to a string equal to your name and build <code>myStr</code> with <code>myName</code> between the strings <code>"My name is "</code> and <code>" and I am well!"</code>
</section>

## Tests
<section id='tests'>

```yml
tests:
  - text: <code>myName</code> should be set to a string at least 3 characters long
    testString: assert(typeof myName !== 'undefined' && myName.length > 2);
  - text: Use two <code>+</code> operators to build <code>myStr</code> with <code>myName</code> inside it
    testString: assert(code.match(/["']\s*\+\s*myName\s*\+\s*["']/g).length > 0);

```

## Challenge Seed

<div id='js-seed'>

```js
// Example
var ourName = "freeCodeCamp";
var ourStr = "Hello, our name is " + ourName + ", how are you?";

// Only change code below this line
var myName;
var myStr;


```

</div>


### After Test
<div id='js-teardown'>

```js
(function(){
  var output = [];
  if(typeof myName === 'string') {
    output.push('myName = "' + myName + '"');
  } else {
    output.push('myName is not a string');
  }
  if(typeof myStr === 'string') {
    output.push('myStr = "' + myStr + '"');
  } else {
    output.push('myStr is not a string');
  }
  return output.join('\n');
})();
```

</div>
